document

The origin of the word " proof" is "belegen" or "prove". Ininformation technology, a document is a medium or data carrier that is suitable for proving the content of certain contexts or facts.

The document is therefore the verifiable and reproducible documentation of an executed action. The form of a receipt is completely different and can be a receipt or a sales slip, a fax or e-mail. For data applications and archiving, the document form is often required by law or legal regulations. Document readers are available for the automatic capture of documents.
